See those birds? Horde. That door? Horde. Car? Horde. Artillery Cannon? Horde. Yes, we triggered the horde more than a handful of times last night. And by we, I mean Mike. But it's ok. That's why we are playing Back 4 Blood - to get dem zombies.
Our playthrough continues this time through three missions, ending Act 1 and starting Act 2.
Needless to say, we had a blast. There's a good variety in the missions that make them a bit more puzzle-like and encourage jolly cooperation. We were damn near surgical on The Sound of Thunder. SURGICAL.
